Introduction to the Top 10 ADAS Systems
Advanced Driver Assistance System Advanced Driver Assistance System, proactive judgment and preventive measures before the driver reacts in an emergency, non-autonomous driving, mainly by carUse various sensors to collect environmental data inside and outside the car, identify/track stationary/moving people/objects

• Sensing Layer: Information Gathering
  • millimeter wave radar, ultrasonic radar, infrared radar, lidar, CCD CMOS image sensor and wheel speed sensor
• Control layer: analyze and process the collected information, and issue action instructions to the control execution device
• Execution layer: accelerator, brake, light, sound

10 major systems

Bold system will make control (light, speed, braking, etc.), non-bold only warning

• LDWS Lane Departure Warning System
  • Suddenly deviate from the lane when driving without turning on the turn signal, and issue a warning
  • HUD heads-up display, camera, controller, sensor
• LKS Lane Keeping System
  • Possible to leave the driving lane, alerted by steering wheel vibration/sound
  • Camera
• ACC Adaptive Cruise Control
  • The front is clear, keep the maximum cruising speed and drive forward, reduce the speed when there is a new target
• FCW Front Collision Prevention System
  • Determine the distance, bearing, speed of the vehicle and the vehicle ahead, and warn if there is danger
  • Measure the distance ahead
• APA Automatic Parking System
  • Identify valid parking spaces and control parking
  • Ultrasonic radar USS, camera AVM look around to perceive parking environment, IMU, wheel sensor to estimate vehicle attitude (position direction), calculate parking trajectory, precise positioning & calculation
• BSD Blind Spot Detection System
  • The rear radar detects the vehicle's rear and side status
• DFM Fatigue Warning System
  • Visual tracking, target detection, motion recognition, etc. for driving behavior & physiological state detection, fatigue, distraction, phone calls, smoking, etc. will alarm within the system set time to avoid accidents
• ALC Adaptive Lighting Control
  • Perceive operations, vehicle driving status, road changes, weather conditions, etc., control real-time up, down, left, and right lighting angle adjustments
  • sensors, ecu, light control systems, headlamps
• AEB Automatic Emergency Braking
  • Provides safe, accurate, real-time imagery and traffic information on the road ahead
  • Microwave radar, lidar, video system
• NVD Night Vision System
  • Active infrared illumination, low-light night vision technology, infrared thermal imaging technology, help to see objects that cannot be seen with high beams
  • UFPA detection sensor, LCD head-up display
